Storage battery

Abstract

A storage battery having at least two plate-shaped individual cells. Each individual cell has at least one housing wall with projections which lie against a housing wall of the adjacent individual cell while forming channels for a cooling medium. Two mutually adjacent and facing housing walls of two individual cells are electrically conductivity connected, at least at the points of contact of the projections, to form a current conductor, the respective walls being of a different polarity for the respective cells of which they are a part.
